Technical Field
[0001] This utility model relates to the field of road protection structure technology, and in particular to a road protection structure for highway engineering construction. Background Technology
[0002] Highway construction is a comprehensive construction activity that includes a series of complex procedures such as route planning, land leveling, roadbed construction, pavement laying, and installation of various traffic facilities. Its aim is to build a safe, efficient, and durable highway transportation system. During construction, road protection structures play a vital role in ensuring the safety of the work area and maintaining traffic order in the surrounding area. They can effectively isolate the construction site from external access areas, reduce the risk of accidents, and protect construction personnel and facilities from external interference.
[0003] Traditional road protection structures used in highway construction mainly consist of foundations, posts, crossbars, outer protective panels, and warning signs. The foundation is typically made of poured concrete, providing a stable base for the entire structure. The posts, usually made of metal, stand vertically on the foundation and are the key vertical components supporting the entire structure. Crossbars, also mostly made of metal, connect the posts and enhance the structure's stability and overall integrity. The outer protective panels are often made of thin metal or plastic sheets, attached to the crossbars through welding or bolting to form a direct barrier. Warning signs, using prominent colors and patterns, are placed in conspicuous locations on the protective structure to alert passing vehicles and pedestrians to the construction area.
[0004] However, its installation method lacks flexibility and convenience. It often uses welding to fix the outer protective plate and crossbars. While this connection method offers extremely high strength, it is extremely inconvenient to disassemble, requiring specialized cutting tools to break the weld points for separation. Even with bolted connections, the bolts are susceptible to rust and corrosion from rainwater due to long-term exposure to the outdoor environment, resulting in an abnormally tight fit between the bolts and nuts, making them difficult to loosen and disassemble. Furthermore, traditional protective structures are not designed to accommodate the frequent disassembly and assembly of the outer protective plate, lacking easily operable quick-assembly structures or devices. This means that in actual construction, adjusting the protected area, replacing damaged outer protective plates, or relocating the protective structure often consumes significant manpower, resources, and time, severely impacting construction efficiency, increasing costs, and, in emergencies, allowing delays in disassembly and assembly to further exacerbate safety hazards. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a road protection structure for highway construction, which aims to improve the problem that the outer protective plate of the traditional road protection structure is difficult to disassemble and install. When it is necessary to adjust the protection area, replace the damaged outer protective plate, or relocate the protection structure, a lot of manpower, material resources and time are often consumed, which seriously affects the construction efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road protection structure for highway engineering construction, including a fixed frame, a protective plate slidably connected to the top of the fixed frame, a protective component provided on the side wall of the protective plate, and an adjustment component provided on the side wall of the protective plate;
[0007] The protective assembly includes a crash plate disposed on the side wall of the protective plate. A connecting post is slidably connected inside the crash plate. The connecting post is slidably connected inside the protective plate. A stud is threaded inside the connecting post. A throttle is fixedly connected to the side wall of the stud. A locking post is slidably connected inside the connecting post. Multiple ball bearings are slidably connected inside the locking post. The ball bearings are slidably connected inside the connecting post and the protective plate. One end of the connecting post is fixedly connected to the side wall of the locking post, and the other end is fixedly connected to the side wall of the stud.
[0008] Furthermore, the adjustment assembly includes fixing members, and a plurality of the fixing members are fixedly connected to the side wall of the fixing frame.
[0009] Furthermore, each of the fasteners has a slot inside, and multiple fastening plates are fixedly connected to the side wall of the protective plate.
[0010] Furthermore, each of the fixed plates has a side plate fixedly connected to its side wall, and a connecting shaft is fixedly connected inside the side plate.
[0011] Furthermore, a retaining ring one is rotatably connected to the outer wall of the connecting shaft, and a retaining ring two is rotatably connected to the outer wall of the connecting shaft.
[0012] Furthermore, both the first and second retaining rings are fixedly connected to a pressing plate on their sidewalls, and the first and second retaining rings are slidably connected inside the retaining groove.
[0013] Furthermore, a spring is provided on the side wall of the button.
[0014] Furthermore, one end of the spring is fixedly connected to the side wall of the fixing plate, and the other end of the spring is fixedly connected to the side wall of the pressing plate.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, the throttle, when subjected to force, causes the stud on its side wall to slide inside the connecting column. This ultimately allows the ball bearings on the outer wall of the locking post to slide out from inside the connecting column, locking or removing the bumper plate and protective plate. This allows for timely disassembly and replacement of the protective plate without replacing the entire protective structure. Compared to traditional protective structures where disassembly is difficult and requires complete replacement, this improves maintenance efficiency and reduces costs.
[0017] In this invention, when the pressing plate is subjected to force, it will cause the retaining rings one and two on its side wall to rotate on the outer wall of the connecting shaft, which will eventually allow the protective plate to be vertically displaced inside the fixing frame. It can be reset and fixed at a suitable height by the tension of the spring. It can be flexibly adjusted according to the specific stage of construction, always providing the most suitable protective height and effectively ensuring construction safety.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-2 An embodiment of this utility model is provided: a road protection structure for highway construction, including a fixed frame 1, a protective plate 2 slidably connected to the top of the fixed frame 1, a protective component provided on the side wall of the protective plate 2, and an adjustment component provided on the side wall of the protective plate 2;
[0025] The protective assembly includes a crash plate 3, which is disposed on the side wall of the protective plate 2. A connecting post 4 is slidably connected inside the crash plate 3 and is slidably connected inside the protective plate 2. A stud 6 is threaded inside the connecting post 4 and a throttle 5 is fixedly connected to the side wall of the stud 6. A locking post 7 is slidably connected inside the connecting post 4 and multiple ball bearings 9 are slidably connected inside the locking post 7 and inside the protective plate 2. An 8 is disposed inside the connecting post 4, with one end fixedly connected to the side wall of the locking post 7 and the other end fixedly connected to the side wall of the stud 6.
[0026] Specifically, when faced with the need to disassemble and assemble the crash barrier 3 and the protective plate 2, the first step is to turn the handle 5. After the handle 5 is subjected to force, it will drive the stud 6 on its side wall to slide in a specific direction inside the connecting column 4. During the sliding process of the stud 6, it will exert a squeezing effect on the connected component 8 and push the locking column 7, so that the locking column 7 will also slide accordingly inside the connecting column 4. As the locking column 7 slides, the ball bearing 9 on its outer wall will slide out from inside the connecting column 4. After the ball bearing 9 slides out, the crash barrier 3 and the protective plate 2 can be locked or removed. With this convenient disassembly and assembly method, when the protective plate 2 is damaged or needs to be replaced, it can be removed and replaced with a new protective plate 2 in a timely manner, instead of having to replace the entire protective structure once a partial problem occurs, as is the case with traditional protective structures. This advantage greatly improves the efficiency of maintenance, reduces the time spent on repairing the protective structure, and allows the equipment or facilities to be restored to normal use more quickly.
[0027] Reference Figure 3 The adjustment assembly includes a fixing member 10, multiple fixing members 10 are fixedly connected to the side wall of the fixing frame 1, and each fixing member 10 has a slot 11 inside. Multiple fixing plates 12 are fixedly connected to the side wall of the protective plate 2, and a side plate 13 is fixedly connected to the side wall of each fixing plate 12. A connecting shaft 14 is fixedly connected inside the side plate 13. A retaining ring 15 is rotatably connected to the outer wall of the connecting shaft 14, and a retaining ring 2 16 is rotatably connected to the outer wall of the connecting shaft 14. A pressing plate 17 is fixedly connected to the side wall of both retaining ring 15 and retaining ring 2 16. The retaining ring 15 and retaining ring 2 16 are slidably connected inside the slot 11. A spring 18 is provided on the side wall of the pressing plate 17. One end of the spring 18 is fixedly connected to the side wall of the fixing plate 12, and the other end of the spring 18 is fixedly connected to the side wall of the pressing plate 17.
[0028] Specifically, when the height of the protective plate 2 needs to be adjusted, the button 17 is pressed first. After the button 17 is subjected to force, it will cause the retaining rings 15 and 16 on its side wall to rotate around the axis on the outer wall of the connecting shaft 14. During this rotation, the retaining rings 15 and 16 will gradually slide out of the retaining groove 11 inside the fixing member 10. In this way, the original locking state of the fixing member 10 is released. With the locking state released, the protective plate 2 can move vertically inside the fixing frame 1. When the protective plate 2 moves to the appropriate height position, it can be adjusted by the tension of the spring 18. By resetting and fixing the height, this adjustment method allows for flexible adjustments based on the specific stage of construction and actual needs. In the early stages of construction, a lower protective height may be needed to facilitate basic operations by construction personnel; while in the later stages, as the project progresses, a higher protective height may be required to ensure safety over a wider area. This ensures that the most suitable protective height is always provided, effectively avoiding safety hazards caused by inappropriate protective height, ensuring the safety of personnel and the smooth progress of the project during construction, reducing delays and economic losses caused by safety accidents, and improving the safety and reliability of construction.
[0029] Working principle: When it is necessary to disassemble and assemble the anti-collision plate 3 and the protective plate 2, turn the handle 5. After the handle 5 is subjected to force, it will drive the stud 6 on its side wall to slide inside the connecting column 4. This process will drive the stud 6 to squeeze 8 and push the locking column 7, so that the locking column 7 also slides inside the connecting column 4. Furthermore, the ball 9 on the outer wall of the locking column 7 slides out from inside the connecting column 4 and locks or removes the anti-collision plate 3 and the protective plate 2. It can disassemble and replace the new protective plate 2 in time without replacing the entire protective structure. Compared to traditional protective structures where disassembly and reassembly are difficult and require complete replacement, this improves maintenance efficiency and reduces costs. When the height of the protective plate 2 needs to be adjusted, pressing the button 17 will cause the retaining rings 15 and 16 on its side wall to rotate on the outer wall of the connecting shaft 14. This rotation causes the retaining rings 15 and 16 to slide out of the slots 11 inside the fixing member 10, releasing the locking state of the fixing member 10. This further allows the protective plate 2 to move vertically inside the fixing frame 1 and be reset and fixed at a suitable height by the tension of the spring 18. It can be flexibly adjusted according to the specific stage of construction, always providing the most suitable protective height and effectively ensuring construction safety.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
